constants inside structs, and typo suggestions for fields and static members

const NAME = e; inside a struct body declares a compile-time constant named
Struct.NAME, reached as Struct.NAME or by bare name in the struct's methods.
A misspelled field or Struct.name member now ends its error with
'; did you mean 'name'?' on the member word, which the language server
turns into a quick fix.
